Write a structure in local scope program using C language

Structure is a collection of different datatype variables, grouped together under a single name.

Features of structure

The features of structure are explained below −

• It is possible to copy the contents of all structure elements of different datatypes to another structure variable of its type by using an assignment operator.

• For handling complex datatypes, it is better to create a structure within an another structure, which is called as the nested structures.

• It is possible to pass an entire structure, individual elements of a structure and an address of structure to a function.

• It is also possible to create the structure pointers.

Declaration of structures

The general form of structure declaration is as follows −

datatype member1; struct tagname{    datatype member2;    datatype member n; };

Here, struct is the keyword.

   tagname specifies name of structure.

   member1, member2 are the data items.

For example,

struct book{    int pages;    char author [30];    float price; };

Example

Following is the C program for structure in local scope −

 Live Demo

#include<stdio.h> struct{    char name[20];    int age;    int salary;    char add[30]; }emp1,emp2; int manager(){    struct{       char name[20];       int age;       int salary;       char add[50];    }manager ; manager.age=27; if(manager.age>30)    manager.salary=65000; else    manager.salary=55000;    return manager.salary; } int main(){    printf("enter the name of emp1:");    //gets(emp1.name);    scanf("%s",emp1.name);    printf("
enter the add of emp1:");    scanf("%s",emp1.add);    printf("
enter the salary of emp1:");    scanf("%d",&emp1.salary);    printf("
enter the name of emp2:");    // gets(emp2.name);    scanf("%s",emp2.name);    printf("
enter the add of emp2:");    scanf("%s",emp2.add);    printf("
enter the salary of emp2:");    scanf("%d",&emp2.salary);    printf("
emp1 salary is %d",emp1.salary);    printf("
emp2 salary is %d",emp2.salary);    printf("
manager salary is %d",manager());    return 0; }

Output

When the above program is executed, it produces the following result −

enter the name of emp1:hari enter the add of emp1:hyderabad enter the salary of emp1:4000 enter the name of emp2:lucky enter the add of emp2:chennai enter the salary of emp2:5000 emp1 salary is 4000 emp2 salary is 5000 manager salary is 55000
